The concept of dark energy came about just around the time Space.com booted up.

"García Peñaloza explained that one alternative to the LCDM model is the wCDM model in which dark energy has a constant value, a cosmological equation of state parameter called "w," which represents the balance of the universe's pressure to its energy density."

I take this to mean that 'w' is a factor that might vary. If energy density increases then so does expansion speed caused by dark energy. I assume the energy density is the sea of virtual particles. I can guess that the rougher the sea then the more pressure on the harbour walls (which would move outwards if they could )

The obvious contender for increasing 'w' is a feeding black hole in another universe feeding its white hole - us from time to time. Maybe.
